I've never handled the EZ, but I will say the trigger on my Equalizer is equal to my Shield Plus. It has a short reset and a smooth trigger pull of 5 1/2 pounds measured with my trigger gauge.

The drop safety is in conjunction with the grip safety so the trigger is a single piece and not like the Shield that has the drop safety as part of the trigger itself.

The Shield uses a striker to fire the gun, the Equalizer uses a internal hammer.
